Embodiments of an apparatus, system, and method for chemical synthesis and/or analysis are disclosed. One embodiment of a disclosed apparatus comprises a laminated, microfluidic structure defining a reactor and a separator. Such apparatuses, or portions thereof, generally have dimensions ranging from about 1 micrometer to about 100 micrometers. To implement synthetic processes, disclosed embodiments of the apparatus generally include at least one valve, and often plural, selectively actuatable valves. Detectors, including optical detectors, also can be used to detect product and other materials as they flow by, or are otherwise presented to, the detector. Individual apparatuses may be coupled both in series and in parallel to form a system for making chemical compounds. The apparatus is particularly useful for making compounds requiring iterative reaction schemes, and further can be used to make compounds having morphological structures that resemble the morphology of the apparatus itself, such as dendrimers.
